If you make a dispenser pointing strait up (or down) then the ball is thrown south instead of up (or down).

right, need to add those directions in, for some reason, it is currently only coded for horizontal plane. Will get that done shortly.

Edit: Fixed the problem, will be fixed in the next version uploaded.

Ok, fix for this issue was committed here, I will close this issue once the next version is uploaded to curseforge.
